Abstract

Fraudulent insurance claims pose a significant challenge to the sustainability and efficiency of insurance systems, resulting in substantial financial losses and eroding trust between insurers and policyholders. The complexity and volume of modern data make traditional fraud detection methods, such as manual assessments, increasingly ineffective. This study investigates the application of machine learning approaches, including Random Forest and Artificial Neural Networks (ANN), to detect fraud in insurance claims. Using a structured methodology, models were trained on historical claim data and evaluated using metrics such as accuracy, F1-score, recall, and precision. The Random Forest algorithm achieved an accuracy of 94%, while the ANN demonstrated superior performance on controlled datasets. Feature importance analysis identified key predictors, including claim amount and submission frequency, offering actionable insights for fraud prevention strategies. The integration of machine learning into claims management systems provides a scalable, accurate, and cost-effective solution to combating fraud. Future research will focus on testing with larger datasets and exploring hybrid approaches to enhance robustness and adaptability.

Abstract

The digital era presents new opportunities in education, including the integration of artificial intelligence (AI) technologies like ChatGPT. This study explores students' perceptions of using ChatGPT in face-to-face learning through a literature review approach. The analysis draws on various reliable sources, including scientific journals, books, and relevant research reports. The findings suggest that ChatGPT is beneficial for helping students understand materials, complete tasks, and enhance their learning motivation. Additionally, it is considered user-friendly due to its simple interface and quick response times. However, several challenges were identified, including limited digital literacy, the risk of receiving inaccurate information, and the potential misuse of the tool as a shortcut, bypassing deeper engagement with learning materials. The study concludes that ChatGPT holds significant potential to support face-to-face learning, especially when used responsibly under teacher guidance. To maximize its effectiveness, efforts should focus on improving students' digital literacy, establishing clear usage policies, and providing structured guidance during the learning process.

Abstract

This research paper explores the extension of COBIT 2019 into a decentralized governance framework, specifically tailored for multi-finance companies in the fintech industry. The fintech sector faces rapid technological advancements, dynamic regulatory environments, and scaling cybersecurity threats; hence, conventional governance models often do not have the flexibility and scalability to cope with these challenges effectively. It addresses these lapses by proposing a framework for governance incorporating the use of decentralized autonomous organizations, blockchain technology for transparency, and artificial intelligence for predictive risk management. The model shall be endowed with smart contracts that guarantee enforcement of compliance in an automated manner, blockchain maintenance of an unalterable audit trail, and the use of AI in finding and mitigating emerging risks in real time. These innovations are also in tune with critical COBOT 2019 domains such as MEA02 (Auditability), APO12 for Risk Management, and DSS05 for Security Services, giving them an all-encompassing and adaptive governance approach. The testing of the proposed model demonstrates significant improvement in operational resilience, regulatory compliance, and stakeholder confidence, especially within high stakes fintech environments. These findings show that incorporating emergent technologies into COBIT 2019 provides added value in governance practices and positions a scalable and future-oriented solution to help navigate the complexities of the fintech sector. This research has contributed to the development of IT governance by showing how a decentralized and technology-integrated framework can transform governance practices in ensuring agility and security within multi-finance operations.
